Although an earlier report suggested separate attackers - one victim described him as a Spanish speaker, the other said he had a Haitian accent - police say just one man is likely responsible for both attacks. In both cases, police say, the man commented on his victim's appearance - and in both cases, the victims managed to escape him.
